Thanks guys. Yes I like it too. It seems to be a bit of a contradiction. The flywheel and wheels as you can see are very nice machined cast aluminium and the piston and cylinder are very well made. Yet the body is just folded up tin plate and I'm fairly sure the boiler is an old aerosol can!
There are some more pictures on my website,
